Orpington

The Orpington was designed by Smith and Milroy who operatated a garage in Orpington, Kent. Their car was in fact what we would today describe as a "kit car" and all the components were sourced from other manufacturers. although the radiator was their own design it could be replaced by that from a Ford Model T.
This was a time before manufacturers had cottoned to the fact that the sale of spares was more lucrative than selling the cars in the first place.
